During the sessions of the Eugenics Exhibition, many exhibitors and 
visitors expressed a desire to possess, for their respective libraries, perma- 
nent photographic and descriptive records of the material on display and 
under demonstration. In response to this demand, the Committee on 
Exhibits before dismantling the exhibition late in October, 1921, photo- 
graphed all of the exhibits which could be reproduced suitably in this 
manner. It prepared also a history and statistical account of the exhibition, 
and made for preservation in permanent form, a careful description of the 
material shown by each of the 131 exhibitors. 
It is trusted that the printing of the account and description of the ex- 
hibition, in systematic form, under one cover, will serve a useful purpose, 
not only to the exhibitors and the persons who are now interested in the 
matter, but also that it will serve an historic purpose in presenting 
graphically a cross-section view of eugenical science at the time of the Second 
Congress, and thus complement the technical papers which were presented 
to the Congress, and which are printed in two volumes bearing respectively 
the titles, Volume I, “Eugenics, Genetics, and The Family,” Volume II, 
“Eugenics in Race and State.” 
It is hoped also that this compilation will be of use to the Exhibition 
Committee of the Third Congress, which can build upon this work in the 
same manner as the present Committee built upon the work of the Com- 
mittee on Exhibits of the First Eugenics Congress, which first committee 
published its account under the title, “Catalog of Exhibits, First Inter- 
national Congress, London, July 24-July 30, 1912, University of London, 
South Kensington.”

12 AN ACCOUNT OF THE EUGENICS EXHIBITION HELD IN 
CONNECTION WITH THE SECOND INTERNATIONAL 
CONGRESS OF EUGENICS IN THE AMERICAN MUSEUM 
OF NATURAL HISTORY, NEW YORK, SEPTEMBER 22 TO 
OCTOBER 22, 1921 
This exhibit consisted of a display of researches into the science and the 
practical application of eugenics and allied subjects. It was shown in 
two sections—first, an exhibit relating to the paleontology of man, 
especially prepared for the occasion by the American Museum of Natural 
History, in the Hall of the Age of Man on the fourth floor; second, the 
Special Eugenics Exhibition, in eighteen alcoves in the Forestry and Darwin 
Halls on the first floor. 
Support. The exhibit was made possible, both by the very generous 
gift of $2,500 for this specific purpose, by Mrs. E. H. Harriman, founder 
of the Eugenics Record Office, and by the American Museum of Natural 
History in providing exhibition space and aid in the installation and care 
of exhibits. 
SECTION ONE 
Anthropology and Archaeology. Hall of the Age of Man. Fourth Floor 
“A special exhibit was prepared by the American Museum of Natural 
History and was installed in the Hall of the Age of Man, which was the 
room where the principal meetings of the Congress were held. Most of 
the permanent exhibits in this Hall were removed, but there remained the 
synoptic exhibit for early man and his culture. 
“On the walls of the hall were the newly installed paintings by Charles 
R. Knight, representing the fauna and other conditions that confronted 
man of the Old Stone Age. Two of these panels represent Neolithic and 
Palaeolithic man respectively. Restorations of extinct races of man are 
shown and compact installations presenting Man’s Place among the 
Primates, The Most Ancient Human Races, and the Immediate Predeces- 
13 14 
EXHIBITS AND EXHIBITORS 
sors of Modern Man, the Neanderthals. The wall space beneath these 
paintings was used for two special exhibits in anthropology: a chronological 
chart and a synoptic exhibit for human culture by N. C. Nelson; photo- 
graphs, face casts, and charts presenting the race problem of Hawaii by 
Louis R. Sullivan. 
“The chronology of the world’s culture prepared by Mr. Nelson, Associate 
Curator of Archaeology in the Museum, is the first serious attempt to 
present the time-relations for the culture of the world as a whole. 
“The Hawaiian exhibit presented the material just returned from an 
expedition to Hawaii, where Dr. Louis R. Sullivan, Assistant Curator 
in the Museum, spent many months under the auspices of the Bernice P. 
Bishop Museum of Honolulu. The charts and busts in the exhibit were 
prepared by the Bishop Museum in Hawaii as their special contribution 
to the Congress. The photographs and mountings were contributed by 
the American Museum of Natural History. Type photographs and busts 
were shown for pure Hawaiians, Chinese, Japanese, and Portuguese, 
accompanied by mixtures of the same. The charts present statistical data 
on the present population. 
“In this Hall also special permanent exhibits, principally those showing 
the restoration of anthropoid skulls and heads, were shown temporarily 
in new positions for the purpose of coordinating and emphasizing geological 
history of the human species.”—Clark Wissler. 
SECTION TWO 
Eugenics and Allied Sciences. Special Exhibition. First Floor 
General Character. The second section, which was shown in the Forestry 
and Darwin Halls on the first floor, comprised mainly embryological and 
racial casts and models, photographs, pedigree charts and tables, biological 
family histories and collective biographies, graphical and historical charts 
on the character and analysis of population, material showing the principles 
of heredity in plants, animals and man, maps and analytical tables demon- 
strating racial vicissitudes, anthropometric instruments, apparatus for 
mental measurements, and books and scientific reprints on eugenical and 
genetical subjects. 
Assembling the Exhibits. Exhibits were secured by corresponding with 
and interviewing persons, in the United States and foreign countries, 
who were known to be interested in eugenical subjects and to be conducting 
eugenical researches. It was aimed to make the exhibits relatively few in 
number but outstanding and specifically illustrating definite principles. 6UG6I7ICS IS ThE

EXHIBITS AND EXHIBITORS 
As the work developed, it was soon found that all of the available space 
would be occupied, and that even some of the exhibits which were offered, 
and which were quite worthy of showing, would have to be represented by 
sample display. 
Exhibitors. The exhibits were shown by scientific investigators in the 
fields of eugenics, genetics, statistics, psychology, anthropology and other 
fields of investigation which bear upon the biological factors in family and 
racial fortunes. College and university professors, investigators in scien- 
tific institutions, physicians and field workers in institutions for the socially 
inadequate, statisticians and research departments of the great life insurance 
companies, scholars and authors of independent means, publishing houses, 
and state and federal governmental departments furnished the main body 
of the exhibits. There were in all one hundred and thirty-one exhibitors. 
Geographical Distribution of Exhibitors. Geographically, the exhibits 
came from twenty-two states, the District of Columbia and sixteen foreign 
countries. By number of exhibits, states and countries were represented as 
follows: Alabama 1, Colorado 1, Connecticut 3, Illinois 4, Indiana 4, Iowa 2, 
Kansas 1, Kentucky 1, Maryland 3, Massachusetts 12, Michigan 2, Missouri 
2, Nebraska 1, New Hampshire 3, New Jersey 6, New York 44, Ohio 4, 
Oregon 1, Pennsylvania 1, Rhode Island 2, Texas 2, Wisconsin 1, District 
of Columbia 10, Australia 2, Belgium 1, Canada 1, China 1, Cuba 1, England 
3, France 1, Holland 1, India 1, Italy 2, Japan 1, Mexico 1, New Zealand 1, 
Norway 1, Peru 1, Switzerland 1. 
Outline of Material Sought. In assembling the exhibits the following 
announcement and explanatory outline was sent to prospective exhibitors: 
Suggestions Relative to Eugenics Exhibits 
It is desired to make the exhibits of this Congress relatively few in number but striking 
in nature. 
All exhibits must pertain directly to eugenical matters, that is, they must have a 
bearing upon the problems of race betterment. Exhibitors are urged to keep in mind 
Galton’s definition that “Eugenics is the study of the agencies under social control 
which may improve or impair the racial qualities of future generations, either mentally or 
physically.” 
While the exhibits must be able to withstand the test of professional scrutiny, still 
they should be of a nature which the man of ordinary intelligence and education, but 
without special scientific training, may readily comprehend and appreciate. Provision 
will be made for exhibiting displays of highly technical work, but the popular aspect will 
be given the preference. 
Charts, maps, pictures, models and scientific apparatus are considered proper means for 
displaying and demonstrating eugenical facts and principles, but any other kind of display 
material which any particular exhibitor cares to offer will be most carefully considered. SECOND INTERNATIONAL CONGRESS OE EUGENICS

offer for display at the forthcoming Eugenical Congress. All such descriptions and offers 18 
EXHIBITS AND EXHIBITORS 
should be in the hands of the Committee by June 1,1921. After that date prompt responses 
will be made to all such offers with the view to coordinating and systematizing exhibits. 
The work of preparing, shipping and installing the exhibits can then proceed in the most 
effective manner. 
All exhibits should be in the hands of the Committee not later than September 1,1921. 
Address all correspondence in relation to exhibits to Harry H. Laughlin, Chairman of 
Committee on Exhibits, Cold Spring Harbor, Long Island, New York. 
Exhibition Space and Installation. The Forestry Hall on the first floor 
of the American Museum of Natural History consists of a central corridor 
or concourse and sixteen alcoves set off by large glass cases eight feet high, 
within which cases the permanent forestry exhibits are installed. Tem- 
porarily the exterior surface of these cases was used for exhibition walls. 
For this purpose the bottom two feet were covered with grey cloth and 
the top six feet by vehisote panels. The running length of these six foot 
panels was 1040 feet. Besides this space, the movable standard screens of 
the Museum were placed within the booths, thus adding approximately 
one-third to the wall space made available by the continuous panels. Down 
the center of the Hall were placed a series of the standard glass exhibition 
cases of the Museum. These cases extended also into the adjacent sections 
of Darwin Hall. All available space was covered by material especially 
assembled for this exhibit, and in a few instances, selection had to be made 
within particular displays offered on account of lack of space. 
Return of Exhibits. All material and packing cases were properly labeled 
upon arrival, and at the termination of the exhibit, the displays were repacked 
and in every case safely returned to their respective exhibitors, or otherwise 
disposed of in accordance with the exhibitor’s instructions. In no case was 
exhibit material lost, nor did any exhibitor express dissatisfaction with the 
handling of his material.

GROUP V. SPECIAL INSTITUTIONS AND METHODS: PERSONAL 
Opening and Attendance. The exhibit was ready on the date announced 
and was thrown open to the public on the first day of the Congress, Septem- 
ber 22, 1921. Special invitation was issued to members of the Congress and 
their friends, and to persons particularly interested in the inborn nature and 
fortunes of races and families. Admission was free. During the month, 
while the exhibit was open to the public, 821 persons signed the register 
to indicate their especial interest in eugenical research, and a desire to pro- 
mote the purpose of the Congress and the exhibit. No exact record was kept 
of the total number of visitors, but Dr. Frederic A. Lucas, Scientific Director 
of the American Museum of Natural History, estimates that between 5,000 
and 10,000 persons attended the exhibit during the month. Attendants 
and guides from the Eugenics Record Office were constantly on hand to 
explain the displays. Special mention should be made also for the courtesy 
and efficiency of the Museum staff in aiding, each in his particular province, 
the work of this exhibit. 
The Eighteen Booths or Alcoves. A description of the general character 
of the exhibits within the several booths. For practical exhibition purposes, SECOND INTERNATIONAL CONGRESS OF EUGENICS 
21 
each of the several booths was numbered, named and given accompanying 
explanatory paragraphs—all posted conspicuously on a placard at the 
entrance of the particular booth, as follows: 
Booth 1. Eugenical Organization. Eugenics is a new science organized from factors 
contributed by may other lines of scientific endeavor. It is based primarily upon the facts 
of heredity, and is properly defined as “The science of the improvement of the human race 
by better breeding” (Davenport), or as “The study of those agencies under social control 
which may improve or impair the qualities of future generations either mentally or physi- 
cally ” (Galton), or “The conscious (as opposed to the instinctive) self-direction of human 
evolution.” 
In this country such agencies as the Eugenics Record Office and the Eugenics Research 
Association are devoted exclusively to promoting eugenical interests. There are a’so 
many colleges and universities which give courses in the new science, and many local 
societies and state institutions which are conducting first-hand eugenical investigations. 
Note: On the tables in this booth there are provided papers and pamphlets on eugenics. 
Persons who are especially interested are given the opportunity to receive blank schedules 
prepared by the Eugenics Record Office for the purpose of guiding investigators in 
securing and tabulating family history data on the biological or inborn trait basis. 
Also, this booth contains the bulletin board for announcing current and forthcoming 
features of the Congress, and especially for posting the time and place of special demon- 
strations by exhibitors; the register for recording the names, addresses and special interests 
of persons especially concerned with eugenics; it is also the office of the exhibit and the 
headquarters of the guides and attendants. 
Booth 2. Genetics and Heredity. Genetics is the science of reproduction and heredity 
in plants, animals and man. Genetics is also an important foundation factor in eugenics 
or the improvement of the human race through a knowledge of heredity and its application 
to selection and fecundity. The determination of a principle of inheritance in one of the 
three groups of organisms throws much light upon genetical behavior in the other two. 
Ultimately the human species must be highly specialized in race and hereditary family 
traits, but in no case must the soundness of stock and high fecundity be sacrificed 
Practical eugenics works in two directions. First, for cacogenic control which seeks 
to raise the level of inborn human values by cutting off the descent lines of those individuals 
who are so meagerly or defectively endowed by nature that their offspring are unable to 
care for themselves and consequently entail a drag upon the more effective members of 
society. 
Second, the aristogenic or constructive activities of eugenics seek to raise the general 
level of inborn human values by securing fit matings and higher fertility among families 
most highly talented by nature in body, mind and temperament. 
Booth 3. Domestic Breeds. The breeders or improvers of domestic plants and animals 
apply the principles of heredity in a practical manner. In order to do this intelligently, 
they must understand the laws of genetics, must see to it that fit matings are made, that 
only those individuals most splendidly endowed by nature, in body and reaction, are 
permitted to reproduce, and that, among the more desired strains, high fecundity is 
secured. 
Man can learn from his own experience with the domestic animals and plants. The 
breeder’s records enable him to direct the forces of racial evolution along definite and pre- 22 
EXHIBITS AND EXHIBITORS 
selected lines. Human eugenics is not stock breeding, but its racial progress depends 
upon such social laws and customs as will direct mate selection along lines which will 
produce offspring of the most highly talented and fertile nature. 
Practical breeders insist on authentic and permanent pedigree records. Man, subject 
to the same laws of natural inheritance as plants and animals, has not yet put into practice 
a universal system of maintaining trait or performance records of all members of the family 
tree. The keeping of trait-records is a necessary step which must precede practical 
eugenics. 
Booth 4. Human Heredity. Hereditary qualities, mental, physical and temperamental, 
are the materials out of which traces are made. Variation in these qualities permits selec- 
tion in the direction of inborn family or racial ideals. It is essential that the manner of 
inheritance of specific human traits be determined by accurate family history study and 
careful pedigree analysis. 
Booth 5. The Family, Mate Selection, Fecundity. The family organization, and the 
laws and customs governing human reproduction, constitute the agency by which racial 
destiny is now determined. Mate selection [in man is governed by courtship and marriage 
and is, of course, one of the greatest of all eugenical factors. Wise matings and high 
fecundity mean racial progress. Unfit matings mean racial degeneracy. At present, 
factors of mate selection, through courtship, are charming personal qualities, high social 
position, wealth and the like. If the race is to improve eugenically, inborn family qualities 
must, ultimately, through education, become important factors in courtship, and con- 
sequently in mate selection. It is eugenically important that each family maintain a 
permanent record of family traits. 
Booth 6. Aristogenic Families. As evidence of eugenics, we find in some families a 
predominance of mental, physical and moral personal qualities of a highly herditary nature 
and of the greatest individual and social value. Such families are called aristogenic. 
A democracy, in common with the science of eugenics, recognizes the aristocracy of 
personal ability, physical, mental and moral. A democratic nation, in order to live, must 
foster good blood and hereditary talent, just as assiduously as an undemocratic country 
fosters special privilege. 
Booth 8. Variation Under Domestication. In his “Plants and Animals under Domesti- 
cation,” Darwin demonstrated conclusively the practical effectiveness of artificial selection 
in establishing new varieties. The permanent Museum exhibits of this booth illustrate this 
truth. 
Booth 9. Variation Under Natural Isolation. Even under a uniform environmental 
condition, members of a uniform species, when permanently isolated, tend to vary in 
diverse directions. Thus the limits of opportunities for mating, in bisexual species, are 
the limits of permanent race-uniformity. 
In isolated American communities, man (both pre-Columbian and post-Columbian) 
has mutated along unique lines and has developed into new varieties. 
Booth 10. Institutions, Administration, Eugenical Education. Many states and institu- 
tions are now recognizing the necessity of working out practical eugenical programs. 
Many custodial institutions (for the feebleminded, insane, criminalistic and the like) 
are making family history studies of their inmates, and many states are denying parent- 
hood to individuals whose handicaps are based upon hereditary defects, and, as a radical 
measure, fifteen states have enacted laws providing for sexual sterilization of certain 
types of defectives. SECOND INTERNATIONAL CONGRESS OF EUGENICS 
23 
Eugenical education is depended upon to develop, in the next generation, a general 
appreciation of eugenical principles, which will result in more highly essential laws govern- 
ing marriage and reproduction, and will influence mate selection in the direction of higher 
eugenical fitness. 
Booth 11. Races of Man. Humanity is composed of many races differing widely in 
physical, mental and moral qualities. The history of the origin and development of 
races and the analysis of the family distribution of personal qualities furnish material 
for the determination of the hereditary nature of specific traits. 
Booth 12. Races of Man. There must always be highly diversified races and highly 
specialized families within races. In order to survive, it is necessary that a given race 
or a given strain have some of the common foundational human elements, such as stamina 
and high fecundity, but in addition to these elementary qualities, racial and family speciali- 
zation is essential in human progress. 
Booth 13. Human Migration, Immigration. Whenever two races come in contact for 
a long period of time, history proves that race mixture follows. Consequently the eugeni- 
cal importance of human migration cannot be over-estimated. It is one of the four or 
five elementary factors which determine racial fortunes. 
Booth 14. Anthropometry. In the scientific study of human heredity, it is necessary 
first to have an accurate standard for measuring specific traits. When these traits are 
physical ones, eugenics draws upon the science of anthropometry for its standards and 
technique. 
Booth 15. Mental Testing, Psychiatry. The recent development of the science of 
measuring mental qualities and physiological and temperamental reactions, has added 
much to the efficiency of eugenical studies. The accurate tracing of psychological 
qualities from one generation to another must rest on a quantitative basis. 
Psychiatry, the study of mental disorders, has contributed much to the proper under- 
standing of the mental mechanism and the human behavior. 
Booth 16. Population, Vital Statistics. The statistical study of population by sex, 
age, race, occupation,literacy, wealth and individual talent reveals the end results of the 
working out of eugenical factors. The study of population and vital statistics constitute 
the bookkeeping aspect of eugenics. 
Booth 17. Eugenics and Euthenics. Eugenics means well born. It refers to improve- 
ment of the human race by better breeding. The whole group of external factors which 
affect human development and which may influence indirectly the course of heredity, 
are called euthenics. Thus if eugenics stands for hereditary factors, euthenics stands for 
the total of environmental forces. Both good heredity and good environment are abso- 
lutely essential to racial welfare. 
Booth 18. Environment, Human Evolution. With the change of environment, especially 
in climate, races of man have been stimulated to migrate from less favorable to 
more favorable regions. These migrations have influenced very greatly the evolution of 
mankind, largely through the struggle for existence, new opportunities for mate selection, 
and the influence of the complex of environment upon differential fecundity and survival.

trotters. His son, Peter Volo, made world trotting records for two-year-olds, three-year- 
olds, and four-year-olds and is now a successful sire. 
Fair Play is a successful sire, but his most valuable get has been Man O’War who, as 
a three-year-old, holds five world records against horses of all ages, marking him as the 
outstanding race horse produced by the breed to-day. He is to-day worth more money 
than any other live animal of any breed. SECOND INTERNATIONAL CONGRESS OF EUGENICS

Photographs of sheep were shown to illustrate the value of good blood in improving 
common stock. The same flock of scrub ewes on the Kentucky Experiment Station farm 
were bred one year to a scrub male and a flock of scrub lambs produced. The next year 
the same flock of scrub ewes was bred to a Rambouillet registered ram and lambs from this 
cross formed a contract to the lambs produced by a scrub sire out of the same dams. The 
lambs by the pure bred sire were worth two to three times the get of the scrub sire.

School, 193 Jefferson Avenue, Brooklyn, N. Y. 
Exhibits: Composite photographs showing racial types of pupils of the Girls’ High 
School. The exhibit from the Girls’ High School, Brooklyn, N. Y., was intended to show 
the racial and national make-up of an average group of 150 unsorted pupils in one of the 
High Schools in New York City. 
In the spring of 1921 a questionnaire was sent to each room in the school asking for 
the following information: 
(1) What is the number of foreign born girls in the room and in what country was each 
born. 
(2) What is the number of American born girls in the room whose father or mother was 
foreign born, and give the foreign country in which either or each was born. 
(3) Give the number of American born girls and the countries to which they trace 
their ancestry (the answer not included in 2). Indians only regarded as of American 
ancestry. 
The answers to the questionnaire are summarized in the following table:

The pupils on register in the school numbered 2200. The table shows Russia contribu- 
ting more than any other country. Nearly all of the Russians are Jews. Austria stands 
next to Russia. Most of the Austrians are Jews. Germany stands third on the list and 
contributes Jews as well as Nordics. England and Ireland stand fourth and fifth respec- 
tively, with Italy sixth. The influence of the remaining European countries is negligible 
in determining the personnel of the school. 
The composite photographs show the types of the several different races and nationali- 
ties. 
Altogether the data show the foreign make-up of the school and the types contributing 
their blood and traditions to the future American. 
21. Exhibitor: Dr. Myrtelle M. Cana van, Pathologist to the Massachusetts Depart- 
ment of Mental Diseases, 74 Fenwood Road, Boston, Mass. 
Exhibits: Enlarged photographs of 50 feebleminded brains and 50 criminal brains 
(Plate 22, Vol. I.). The exhibit from the laboratories of the Massachusetts State Psychia- 
tric Institute consisted of enlarged photographs of the superior surface of (a) 50 feeble- 
minded brains, and (b) 50 criminals. 
The first 10 of these feebleminded brains have been intensively studied and published 
in monograph form in the Memoir Series from the American Academy of Arts and Sciences; 
Vol. XIV, No. II, May 1918, as Waverly Researches in the Pathology of the Feeble- 
minded (Research Series, Cases I-X), by Walter E. Fernald, E. E. Southard and Annie 
E. Taft, and the second 10 of the same 50 exhibited appears as the continuation of this 
clinico-anatomical study as Vol. XIV, No. Ill, November 1921, Memoirs of the American 
Academy of Arts and Sciences, Waverley Researches in the Pathology of the Feeble- 
minded (Research Series XI-XX) by Fernald, Southard, Canavan, Raeder and Taft. 
The aim of the first monograph was to discover which types of feeblemindedness were 
preventable, if brain complexity was measurable, and if hydrocephalic dilatation of 
ventricles contributed to outbursts of excitement. The second monograph indicates 
the answer of the question of matching testable mind with measurable brain and points 
toward one type of preventable feeblemindedness, e.g., syphilitic. 
The pictures exhibited will form the basis of the completed monograph on Feebleminded- 
ness. Attached to each picture was a brief explanatory chart giving the brain weight, SECOND INTERNATIONAL CONGRESS OF EUGENICS

the mental and chronological ages and such facts as were known concerning the heredity, 
which rarely exonerated the family, and the brains themselves presented anomalies of 
fundamental character—lack of furrows—interlocking of hemispheres, stenciling of surface 
pattern, or marked microcephalia. 
Hydrocephalous enlargement also was a marked though infrequent finding, and evi- 
dence of old meningitis could be seen. 
The brains (b) of 50 insane criminals also formed a portion of the exhibit and presented 
striking differences from the feebleminded in that no microcephalic nor hydrocephalic 
were present in a similar series of 50. The most striking feature was that their brains 
were, for the most part, either very long or very round, with well developed pattern, 
probably indicating that the criminal is potentially well endowed but improperly uses his 
endowment. Most of the crimes were minor ones—breaking and entering, drunkenness, 
vagrancy, now and then a major crime of murder. It was striking, perhaps fortunate, 
that the majority of these men were unmarried. 
22. Exhibitor: Dr. Chester L. Carlisle, Director Oregon State Survey, Chief, Neuro- 
Psychiatric Section, U. S. Veterans’ Bureau, Leiter Bldg., Chicago, 111. 
Exhibits: Two charts showing percentage findings of Oregon State Survey. 
The Oregon State Survey of Mental Defect, Delinquency and Dependency, conducted 
by the University of Oregon, under the direction of the United States Public Health 
Service, was unique in that it was the first survey in mental hygiene ever carried on without 
special state appropriations, the work being accomplished by the voluntary aid of thousands 
of citizens chiefly recruited from the professional, educational and official groups in each 
village, city and county of the state. The Survey may be divided into two main divisions: 
(1) A survey of the community at large. The findings in this division show the number 
of socially inadequate persons of all classes in the community, not including school children 
in the schools. One chart of this exhibit deals exclusively with such community findings 
and points out the type of mental, physical or social disorder which rendered the individual 
inadequate. Broadly speaking, such types are essentially the insane, the mentally 
deficient without psychosis, the socially inadequate (frequently mentally abnormal) 
delinquent type, and the socially inadequate (especially the mentally defective) dependent 
type. 
(2) The second division of the Oregon State Survey comprised an analysis as to why 
children actually in school were over-age for their grades and are thus considered to be 
retarded in school work in comparison with normal age expectations. The chart setting 
forth the major findings of this school survey shows the percentage of over-age for grade 
school children who are actually mentally dull or subnormal. The chart demonstrates 
that a child who is definitely over-age for grade has a specific reason for such retardation; 
and that taken as a whole, apparently one-third of such retarded children are considered 
by their teachers, or others who have been able to observe them closely, as showing a 
definite degree of mental dulling. This survey brought out that purely physical disorders 
as such, were not responsible for as large a percentage of school retardation as was formerly 
thought to be the case. Causal factors relating to parental inadequacy loom large. 
Parents carrying recessive unit characters which make for organ weakness in offspring, 
produce children who show their first social inadequacy from a practical standpoint as 
over-age for grade pupils in school. Conversely, socially inadequate adults have almost 
without exception, a history of having been over-age for grade in school. Prophylaxis in 
mental hygiene finds a wonderful field in reviewing the possibilities to be found in the 
school which are molding the minds and habits of the coming generation. 30

Exhibits: One book: “The Eugenic Prospect—National and Racial,” by C. W. 
Saleeby, M. D., F. R. S. E., F. Z. S. In this volume the author, who abandoned medical 
practice in 1904 to follow Francis Galton, the founder of modern eugenics, gives the result 
of his studies of personal, national and racial health. Our scientific knowledge, especially 
of food and drink, has greatly advanced since the Armistice; vital statistics, and especially 
the quality of the birth rate, have shown grave tendencies. Dr. Saleeby, as delegate to 
certain international congresses concerned with public health in 1919 and 1920 took the 
opportunity to make wide observations in sixteen countries, the results of which are given 
a prominent place in the present work.

These three portrait figures are reproduced in photogravure from original photographs, 
magnified about fifteen to eighteen diameters—the original heads being about one centi- 32 
EXHIBITS AND EXHIBITORS 
meter high. The original figures are sculptures carved in silver, not chased or stamped, 
found as decorations on a large silver cup, which, on account of its form, proportions and 
decorations, can be dated with certainty to the middle of the first century A. D. when 
vessels of this form were in use. After that century no similar vessels were made, all 
possessing a different and characteristic form. On the cup in question there are in all 
twelve well preserved figures, all made with the same exquisite skill and technic. One 
of the personages is distinctly a Greek, but all the others are Jewish. As all the figures are 
absolutely distinct from each other and exhibit personal characteristics of trait, mental 
and moral characters, and one or two a distinct educated mien, it is obvious that we have 
before us personal portraits of surprising quality and character, quite superior to any 
portraits, painted or sculptured, so far known from the first century A. D. These por- 
traits cannot represent types. None are idealized, but all, on the contrary, reproduce 
with fidelity, it seems, personal characteristics of body and mind, nay, even defects. For 
the study of Jewish personalities in the early part of the Roman Empire, these twelve 
representations are absolutely unique as no similar portraits, executed with such art, are 
previously known. The object on which they are found as part of the decoration, is a 
cup of silver, about 0.19 cm. by 0.15 cm. It was found at Antioch in Syria in 1910, 
and is now in New York. 
41. Exhibitor: Dr. A. H. Estabrook, Eugenics Record Office, Cold Spring Harbor, 
Long Island, N. Y. 
Exhibits: Charts dealing with the Jukes, Ishmaels, Nams, The New Harmony Move- 
ment (Plates 18, 19 and 20, Vol. I). This exhibit comprised four sets of charts. Three 
of these sets referred to cacogenic groups which the exhibitor had studied, the other, 
the story of the New Harmony, Indiana, Experiment in Communism. 
The Tribe of Ishmael, an aggregation of paupers, criminals and wanderers in Indiana 
and neighboring states, is pictured in the next set of charts. The Tribe is numerous, 
at least 10,000 in number. 
The New Harmony experiment in communism, the subject of the last set of charts 
of this exhibit, was carried on in Indiana during the first twenty-five years of the nineteenth 
century. A group of religious enthusiasts from Wurtemburg, Germany, about one thou- 
sand in number, under the leadership of a George Rapp, carried on a community, where 
work and goods were in common and the religious bond held them together. This com- 
munity was very successful materially and the people worked hard building the new 
town in a country at that time a wilderness. They were contented and had a much 
higher standard of living than their neighbors of the wilds. Robert Owen, of England, 
the manufacturer, bought the community property from the Rappites to carry his “New 
Moral World” plan and his scheme for the bettering of the conditions of the working 
classes and all society through free education for every one and common ownership of 
all property and general division of labor. His community lasted a little less than two 
years, the failure being ascribed to various causes. There were shown pictures of the five 
large community houses built for men and women to live in groups; the brick and wooden 
dwellings all erected on the same plan to indicate the equality of all; the big stone church— 
all the foregoing erected by the Rappites. Other pictures show the community under 
Owen’s direction. Photographs or reproductions of paintings of the members of the Owen 
family and other prominent men of the town then, and also a sketch of the town as it is 
to-day, quiet and complacent with its memories of olden days, nestling along the Wabash 
River in the midst of the rich farming land of Posey County. 33 
SECOND INTERNATIONAL CONGRESS OF EUGENICS 
42. Exhibitor: Eugenics Education Society, 11, Lincoln’s Inn Fields, London, W. C. 2, 
England. 
Exhibits: Charts, posters and publications: (1) Set of the Eugenics Review, Vol. I- 
XIII (incomplete). (2) Set of publications of the Society. (3) Charts showing (a) 
inheritance of dramatic and musical ability. (Plate 5, Vol. I). (b) inheritance of defect, 
(c) Mendelian heredity with dominance, (d) Mendelian heredity. Theory of gametic 
purity, (e) Pedigree of the Caesars. (Plate 17, Vol. I). 
The Eugenics Review is the quarterly publication of the Eugenics Education Society, 
London. It has served during the period of its existence (1) to put forward, with a mini- 
mum of technical language, the current state of knowledge in respect to heredity, as 
studied by the Mendelian and by the Biometrical method. (2) For the statement and 
discussion of the general principles involved in questions of race betterment, such as 
historical evidence of deterioration by adverse selection, discussions of the effects of race 
mixtures, etc. (3) For the discussion of individual opinions on the relation of other racial 
questions, marriage laws, divorce regulations, etc., with eugenics. 
The charts are designed to illustrate a few clear and unmistakable cases of the repetition 
of a single congenital trait, or groups of traits, in particular families. They should not 
be read as implying that the trait in question is believed to be inherited as a single Mende- 
lian factor, but as illustrations of the importance of heredity in general in determining 
individual characters.

Exhibits: Photographs of North American Indians. The full-blooded American Indian 
is fast becoming a thing of the past. Negro and white crosses have been so numerous that 
the full-blooded Indians are becoming fewer every year, and these, for the most part, are 
gradually losing the distinguishing features of their particular tribe. After the great 
round-up of the seventies, most of the Indians were located on reservations—part of them 
being some distance from their original camping grounds. This had a marked effect on 
most of the Indians. The high ideals, courage and bravery so characteristic of them 
gave way to broken spirited public wards, either relying upon the government for support 
or attempting to live by the unnatural methods of the white man. Such government 
action was quite necessary, but nevertheless it had a marked effect on the Indians as a 
race. In order to study the distinguishing types of the various tribes, one must go back 
to the time when, with the tribe as a unit, they roamed free and independent. 
The exhibit of typical types of North American Indians is made up principally of 
photographs. The photographs were mostly taken from forty to sixty years ago and 
include the leading and most noted chiefs of the different tribes of the Northern and 38 
EXHIBITS AND EXHIBITORS 
Southern Indians. They offer facial studies and dress, also the opportunity to compare 
statures. Never again will the Indian return to his original condition, and any further 
observation must be made from the living survivors of the old days or from photographs 
which we now have, as it is growing harder each year to obtain likenesses showing the 
independent spirit of the old days when they roamed the plains in freedom.

College, Hanover, N. H. 
Exhibits: Graphic charts relative to the Trend of Longevity in the United States. The 
scheme of constructing abridged mortality tables, explained in the Registrar-General’s 
Report (British) for 1914, was employed, but the work was modified in accordance with 
results presented by the exhibitor in the October, 1919, issue of the Bulletin of the Ameri- 
can Mathematical Society to construct eighteen abridged mortality tables based upon 
the federal population and mortality statistics for the various classifications of the popu- 
lation of the United States for the three years 1890, 1900 and 1910 of the seven states 
(Connecticut, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island and 
Vermont) which were the only states which were registration states throughout the two 
decades 1890-1910, except for the year 1900, when the statistics for Vermont were neces- 
sarily omitted because of the faulty form in which the mortality statistics were published. 
The exhibit then gives the most important results taken from these mortality tables 
with the purpose of showing the probable trend of longevity in the United States. No 
claims are made for any great accuracy in the numerical results themselves since all 
ordinary statistical data of this kind are apt to be somewhat faulty and especially since 
each mortality table is constructed from statistical data for a single year and must reflect 
the peculiarities of that year. The final results of all the tables, however, check sufficiently 
well to warrant considerable confidence in the general trend exhibited. As far as we 
can find, these tables give the first estimates of the longevity of the various groups of 
population covered by the federal statistics.

Exhibits: Curves showing Racial Differences in Mental Fatigue (Plates 33, Vol II.) 
Groups of White, Indian and Negro children were engaged continuously in a more or less 
mental task, i.e., adding one place numbers on sheets already printed for the purpose. 
Records were therefore made on sheets arranged in tablets; two minutes were given 
for working on each sheet. The younger subjects worked 28 minutes; the older 
subjects worked 42 minutes. The younger subjects were students from third and fourth 
grades of public and United States Indian schools and the older subjects were taken from 
seventh and eighth grades of same schools. 
In both columns attempted and columns accurate, the Indians worked with less 
falling away in efficiency toward the end than either the whites or the negroes, and the 
whites excelled the negroes in this respect. 
The curves shown herewith are expressed in terms of average per cents of total work 
of the individuals of a sub-group. By taking the average per cent of work done in the 
first six minutes and bringing it into relation with average work done in last six minutes by 
a sub-group, it was shown that in the lower grades, or the younger groups, in attempts 
the Indians gained 3.25 per cent, whites lost 3.00 per cent and negroes lost 12.10 per 
cent; in accurates the Indians lost 8.40 per cent, wdiites lost 17.60 per cent and negroes 
lost 27.20 per cent. In the upper grades it was thus: Attempts, Indians gained 2.0 per 
cent, whites lost 4.00 per cent, and negroes lost 4.7 per cent; accurates, Indians lost 1.30 
per cent, whites lost 10.20 per cent, and negroes lost 30.30 per cent. SECOND INTERNATIONAL CONGRESS OF EUGENICS 
39 
This and other handling of the data (See Journal of App. Psy., Vol. IV, pp. 235-244, 
and Vol. V, pp. 14—25) indicate that the Indians, who were of the Plains and Forest 
Indian tribes, tend to resist the onset of tendency to fall away in efficiency, or “mental 
fatigue” more successfully than first the whites and then the negroes. It is not 
known what other Indian tribes would do, who are not the Plains and Forest Indian 
stock. 
48. Exhibitor: Dr. John H. Gerould, Dartmouth College, Hanover, N. H. 
Exhibits: Heredity in Pierid butterflies. 
Colias philodice 
The exhibit showed two hereditary variations in caterpillar skin-color, olive and blue- 
green, each of which is directly correlated with a corresponding eye color in the adult 
butterfly. 
A butterfly with olive-green eyes produces olive-green caterpillars. This color is 
recessive to the normal yellow-green eye-color and caterpillar-color. The recessive olive 
mutation not only affects eye-color but also gives an orange hue to the wing scales of the 
butterfly. The under side of the hind wings and the tips of the fore wings, parts most 
directly exposed during pupal development to the action of the blood, are distinctly 
orange in this normally yellow species. The blood (haemolymph), however, is not visibly 
olive or orange. It is of the normal yellow-green color. 
The second mutation, however, is a blue-green variation in blood-color, recessive to 
yellow-green. The butterfly has blue-green eyes, blue green blood, lays pure white (not 
cream-white) eggs, producing conspicuous blue-green caterpillars, which lack the pink- 
yellow lateral stigmatal line. That yellow is entirely left out of the caterpillar was proved 
by the fact that certain hymenopterous parasites that had fed upon the blood of a blue- 
green caterpillar spun not bright yellow cocoons like those spun by such parasites after 
emerging from a yellow-green caterpillar, but pure white cocoons. The cast skin of 
the pupa also lacks yellow. The missing yellow is probably xanthophylloid pigment 
derived from chlorophyl of the food (clover). This variation does not affect the wing- 
color of the butterfly. 
Both of these mutants have appeared in the same family in a 9:3:4 ratio (9 yellow- 
green: 3 olive: 4 blue-green), the double recessives probably being the blue-green cater- 
pillars with a faint orange sheen that we observed in a family of this sort. 
Hybrids 
A hybrid cross between Colias eurytheme (orange) and C. philodice (yellow) was shown, 
demonstrating the incomplete dominance of orange. Fi is intermediate, or pale orange; 
F2 shows segregation of the orange-yellow producing factors. One of the families showed 
also the transmission of a white sex-limited variation in wing-color of the female by an 
orange (eurytheme) son of white female (and the mate of a yellow (philodice) female to 
half of his hybrid daughters, 50 per cent of which were white, 50 per cent pale orange.

EXHIBITS AND EXHIBITORS 
Exhibits: One book. “America: A Family Matter” is a study of the causes which led 
to the downfall of the human intelligence in the Dark Ages. The preliminary discussion 
would seem to show that the thoroughbred is the best animal and that care in reproduction 
is necessary to produce and preserve a fine strain. The argument is that as man is an 
animal, he is governed by the animal law and to produce the finest men physically of any 
one strain, crossmating should be avoided,—in short that the same care should be exercised 
as is taken of our domestic animals. 
It is further argued that in a pure blooded carefully reproduced race, intelligence which 
is based upon the action of a material substance called the brain, will be improved by the 
improvement of the material substance of the brain which, like the muscles and organs of 
the body, will respond to care in reproduction. 
This being the scientific or theoretical side of the question to history, the appeal is then 
made. The stories of Egypt, Greece and Rome are hastily sketched, and in each instance, 
the downfall of the race is found to be practically contemporaneous with hybridizing and 
mongrelization of the people. 
These scientific and historic facts are then applied in a brief way to the study of condi- 
tions in the United States. The deplorable results of our lavish importation of cheap 
labor with the introduction of many different racial strains are noted, and the consequent 
loss of the singular advantage of our afore-time race purity is shown.

54. Exhibitor: Dr. Hornell Hart, Head of the Sociological Divison of the Iowa Child 
Welfare Research Station, Iowa City, la. 
Exhibits: A four-dimensional chart illustrating fecundity in relation to three other 
variables. The data used in the investigation were the returns of the 1915 Iowa State 
census by counties. The index of fecundity used is the number of children under five 
years of age per 1000 women twenty-one to forty-four years of age. This is represented 
on the chart by the vertical dimension. The higher the surface is, the larger is the number 
of children per 1000 women. The three variables with which this index of fecundity is 
correlated are: first, the percentage of the populations of the various counties living in in- 
corporated places; second, the percentage of persons over school age who have attended 
school eight or more years; and third, the percentage of persons twenty-one to forty-four 
years of age owning homes. SECOND INTERNATIONAL CONGRESS OF EUGENICS 
41 
Of these three variables the first—indicating the percentage of urban population— 
is represented by the depth of the chart, from front to rear. It will be noted that the 
back of the chart, representing conditions in almost wholly rural counties, is two or three 
times as high as the front, which represents conditions in counties almost wholly urban. 
This means that the fecundity is very decidedly lower in cities than in rural districts, 
the other two factors being equal. The surface is curved from front to rear. This 
indicates the fact thht in the most rural counties, the presence of small towns makes 
relatively little difference in the fecundity, while in counties containing good sized cities 
the proportion of urban population has much more decided relationship to the birth rate. 
The second variable, indicating the extent of education among adults of the counties, 
is represented in the width dimension of the three in the chart. It will be noted that 
the right hand side of each unit is higher than the left hand. This indicates the fact that 
fecundity is higher in communities with fewer well educated adults than it is in communities 
with a large number of educated adults, provided that the other two variables are constant. 
The third variable, percentage of middle-aged adults owning homes, is represented by 
the positions of the units from right to left. The right hand unit represents fecundity 
when home ownership is at a minimum, the left hand unit represents fecundity when home 
ownership is at a maximum. The fact indicated is that when the other two variables are 
constant, home ownership is inversely correlated with fecundity. If the simple correlation 
between fecundity and home ownership is calculated, it appears that the correlation is 
positive, because home ownership is more common in rural districts than in cities. Partial 
correlation is needed here to bring out the true relationship. 
The tendencies shown by the partial regression surface in the chart may be summarized 
by saying that the highest fecundity tends to occur in rural communities inhabited by 
poorly educated tenant farmers, while the lowest fecundity tends to occur in urban 
communities inhabited by highly educated individuals, a large proportion of whom own 
their own homes.

Exhibits: Reprint of paper on “ Hair Coloration in Animals.” In this the author points 
out the structural characters of hair pigmentation in mammals, and from a cursory survey 
of hair from various races of mankind advances the notion that possibly the character of 
the pigment granules in the cortex of the hair, as well as the character of the patterns which 
they form, may be of use in helping to determine racial affinities. At least there is a 
definite variation (as far as the author has noted) in the shape, size, and color value of 
the pigment granules, and in the shape, size and distribution of the granule patterns 
in the cortex of the hair, in the different races.

59. Exhibitor: Dr. Lucien Howe, Ophthalmic Surgeon, 520 Delaware Avenue, Buffalo, 
N. Y. 
Exhibits: Charts and Demonstration of Hereditary Eye Defects, also living rabbits 
showing “Guyer’s results.” Dr. Lucien Howe, Buffalo, gave a demonstration of hereditary 
blindness in rabbits, produced by serologic methods. These results were obtained first by 
Prof. Michael F. Guyer of the University of Wisconsin. His method was to asphyxiate 
or otherwise kill three or four rabbits, remove the lenses, make an emulsion of the lens 
substance, and inject that emulsion in carefully increasing doses into a fowl until the fowl 
was sensitized to the rabbit lens. 
A female rabbit was then selected, which he had reason to suppose was pregnant about 
the tenth to the fifteenth day, that being the time when the foetal eye was in the process of 
formation. Into this pregnant rabbit, the serum of the sensitized fowl was injected, also 
in gradually increasing doses. As a result, he obtained imperfect eyes in the next genera- 
tion. Then he mated these defectives and secured others, still more defective, until he 
had obtained a whole series. The specimen shown here is one of Prof. Guyer’s rabbits 
which has practically no eyes at all. Most of them have cataract, usually with compli- 
cations. 
A number of pedigree charts were shown in this exhibit, illustrating the different rules 
of inheritance of many eye defects, such as cataract, glaucoma, coloboma, iritis, de- 
formity of inner canthus, etc. 
60. Exhibitor: Dr. Ales Hrdlicka, for the U. S. National Museum and Smithsonian 
Institution, Curator, Division of Physical Anthropology, U. S. National Museum, Wash- 
ington, D. C. 
Exhibits: Variation, Heredity, Reversion, etc., in Man. These exhibits, on account of 
their importance, were given a separate alcove in the Darwin Hall where they filled seven 
cases. They related to Evolution, Variation, Reversion and Inheritance, in different 
parts of the human body. 
Case I was filled with a phylogenetic series of brains of the Primates, including Man, 
cast by the gelatine method from originals hardened in situ (within the skull), and pre- 
served in the United States National Museum. They included the brains of: adult 
gibbon, orang, chimpanzee and gorilla, the first series of adult brains of these apes it was 
ever possible to bring together. The same case also included three racial brains showing 
extremes of variation, under normal conditions, in the brain convolutions. 
In the next five cases the following series was exhibited: Normal variation in the size 
of the skull; in the lower jaw; in the atlas and axis; in the first rib; in the sternum; in the 
scapula; in the sacrum; in the patella; and in the shape of the shaft at middle of the femur, 
tibia and fibula. A series of skulls of the American Indian showed the persistence to this 
day of Neanderthaloid forms and other primitive features. A series of scapulae was 
shown next demonstrating various evolutionary stages of this bone. SECOND INTERNATIONAL CONGRESS OF EUGENICS 
43 
Examples of reversion were presented in a series of humeri showing variously developed 
supra-condyloid processes; and in a series of crania showing various forms of temporo- 
frontal articulation. 
The hereditary transmission of recently acquired characters was illustrated by a series 
of five pre-Colombian crania from one cemetery on the coast of Peru, showing each a 
complete absence of the auditory apparatus on the right side of the skull; and by a large 
series of crania also from Peru, showing the great multiplication and diversification among 
these people of various forms of the so-called “Inca Bone.” 
The seventh case was filled with a series of specimens of hair showing the whole range 
of variation of this feature as met with in the study of upwards of 1800 representatives of 
the oldest American families. 
Finally in an upright case was exhibited a large chart showing the results of measure- 
ments and tests on the Old Americans (Plate 18, vol. II). 
Many of the individual specimens in the above exhibits were of unique nature. The 
main object of the exhibits was to demonstrate the facts of the existence of extensive 
normal variation in all parts of the skeleton as well as the rest of the body; to show that 
with enough material at our disposal we may connect by direct gradations any existing 
form with the form from which it was originally derived; and to illustrate the propagation 
by inheritance of new morphological and even of very definite and important pathomor- 
phological conditions. The chart, finally, of the Old Americans showed clearly conditions 
of direct concern to eugenics in this country.

Exhibits: Photograph of organization and pamphlets. The exhibit of this society 
consisted of a photograph of the Organization Committee. The popular Indian name 
of the society is Hindusthan Jatisudhar Sabha. The society was established at Lahore, 
India, on Monday, June 20, 1921, through the untiring efforts, and in the beginning, 
single-handed, hard work of the Honorary Organizer, Professor Gopalji Ahluwalia. 
63. Exhibitor: Indiana Board of State Charities, 404 State House, Indianapolis, Ind. 
Exhibits: Four charts. Chart 1 outlines the state’s provision for the care of depend- 
ents, defectives and delinquents, under the three heads of state, county and city. 
The governor, at the head of the system, appoints the Board of State Charities, which 
exercises general supervision, the State Board of Accounts, which examines into fiscal 
affairs, and the Board of Trustees of each of the twenty state institutions. Eight of these 
twenty institutions are for mental cases—five for the insane, two for the feebleminded, one 
for the epileptic. There is also, at the State Prison, a hospital for insane criminals. 
Several of these institutions have farm colonies. 
Chart 2 specifies the purpose and duty of the Board of State Charities, and the various 
institutions under its supervision, the expenditures of which amount annually to $6,600,000. 
Chart 3 describes briefly what has been learned to date by the Indiana Committee on 
Mental Defectives, through its survey of ten representative counties. The committee 
has listed 5,322 insane, feebleminded and epileptic persons in these ten counties, from 
which it estimates that 2.1 per cent of the state’s population is defective. The committee 
was first appointed by request of the Board of State Charities. Chart 4 refers to the 
Indiana sterilization law. The law was passed in 1907 and made to apply to confirmed 
criminals, idiots, rapists and imbeciles. Two hundred and eighteen operations were 
performed under it. The law was declared unconstitutional in 1921, on the ground that the 
person concerned was not given a hearing, this constituting a violation of the fourteenth 
amendment to the federal constitution.

Exhibits: Selective fertilization. Pollen from a white, smooth starchy seeded pure 
breeding type of maize when mixed with pollen from a yellow, wrinkled sweet type and 
applied at the same time to the pistils of the two types, gives self and cross-fertilized seeds 
on each inflorescence which can be distinguished. Results from many such pollen mixtures 
show that with maize there is a marked tendency for that plant’s own pollen to be more 
effective in accomplishing fertilization than pollen from related but generically somewhat 
different plants.

(3) Better American Families—Series of papers in Journal of Heredity showing the

Charts: (1) Three charts illustrative of Heredity and Social Fitness in the “Rufer 
Family.” Five lines spring from Aaron Rufer, a strong, plucky pioneer, having good 
ability to calculate, and Mary, his easy-going wife, who was totally lacking in sense of 
number and proportion. Their five children showed noticeable presence or absence of 
these traits, and through their marriages founded widely divergent lines. Founders of 
lines A, B, and C, though weak in certain traits, were superior to founders of Lines D 
and E. Marriage usually occurred with representative of stocks possessing these traits 
in good measure, and has resulted in the practical blotting out of the defects of the founders. 
Founders of lines D and E were markedly defective; marriage usually occurring with 
degenerate offshoots of bad and mixed strains has resulted in line D in many drunkards, 
paupers, prostitutes, and thieves, while line E has been persistently imbecile. 
(2) Chart showing differential migration in the Rufer Family. The active, able 
members of lines A, B, and C have pushed out into other sections of the country, there 
developing its resources and leaving the unfit members (lines D and E) behind to become a 
burden on the public, a physical and moral menace to the community. 
67. Exhibitor: Miss Susan Ricker Knox, Artist-Painter, 219 East 19th Street, New 
York City, N. Y. 
Exhibits: Sixteen paintings in oil colors. Group studies of immigrant types. These 
studies were made while the everyday processes of immigrant inspection at America’s 
greatest receiving station were uninterruptedly going on. They were made in the registra- 
tion room, the railroad room and the deporting and detention room. They had to be made 
swiftly because the groups were constantly shifting, even in the deporting and detention 
room where letters, telegrams and special inquiry orders were constantly being delivered 
and admissions and deportation intermittently going on. The individuals in the groups 
were, in most part, unconscious of being painted—the object of the painter being to get 
them as they were without pose or affectation on their part. 
The pathos of deportation orders, of news of deaths in hospitals of members of the 
immigrants’ families, or delays in arrival of expected friends, funds, letters, or telegrams, 
was constantly making its appeal to the artist’s sympathy and adding to the difficulties of 
the work. 
Most of the canvases portray women and children only, because the greater part of the 
work was done in the women’s section. 
The studies were painted simply because the subject involved thrilled the painter and 
she, in turn, tried to bring out the self-respect, self-restraint and devotion—the spirit 
which characterized the majority of the home seeking immigrants that came under her 
observation. 
68. Exhibitor: Dr. Margaret W. Koenig, Medical Social Service, Lincoln, Nebraska. 
Exhibits: Seventeen pedigree charts showing Heredity of Tuberculosis among the 
Nebraska Winnebago Indians. These charts were constructed as the result of a social 
study on an Indian reservation, with particular reference to tuberculosis. Cf. “Tubercu- 
losis among the Nebraska Winnebago,” published by the Nebraska State Historical 
Society, Lincoln, Nebraska. They represent the family distribution of tuberculosis based 
upon the actual incidence of the disease in the tribe studied and involve one hundred and 
ten single families or over one-third of the families on the reservation. 46 
EXHIBITS AND EXHIBITORS 
All marriages, of which information could be obtained from the family histories, are 
shown on the charts. All unions are marriage by “tribal custom”1 unless designated by 
the term “legal marriage.” Owing to the great frequency of marriage, the line of descent 
is constantly broken. To the extent that it was possible to secure family histories, the 
line of descent is traced principally through the female, and wherever possible, through the 
male line. 
The chief purpose of the charts is to present an intelligible picture of Winnebago 
Indian life—to visualize the incidence of tuberculosis and the environmental factors 
surrounding and contributing to the moral and physical decline of this once fine-looking 
and stalwart people. A glance at the charts convinces one of the wide-spread occurrence 
of the disease. Generally speaking, examination of the charts shows no tuberculosis in 
the first generations and but an occasional case in the second. A few cases creep in in 
the third and in the fourth and fifth generations many cases appear. The number of 
cases per family ranges from two in the smallest to fifty-five in the largest. Some families 
are much more afflicted than others. Family 17 shows the smallest number of cases. 
This is an old type Indian family who still cling to the old traditions and keep up the old 
time customs. Since there has been little intermarriage with other races, the stream of 
blood in this family is almost pure Indian. Another interesting point that the charts 
show is the numerous instances of infected offspring from parents, one of whom is a 
descendant of a tuberculous family.

of this volume. The charts showed graphically the relative and absolute incidence of 
men of very superior talent in several lines of human endeavor by nation and century. 
74. Exhibitor: Mrs. Ruth Moxcey Martin, Woodbury, Conn. 
Exhibits: Chart Showing Survival of Original Surnames in the Town of Woodbury, 
Conn. One of the oldest of American interior settlements was made in 1672 by a group of 
Yankees of Stratford, Conn., who decided to go as pioneers farther inland among Connec- 
ticut hills. Woodbury of the accompanying chart was the result. Cothren, in his history 
of Ancient Woodbury, gives full details of this immigration into land occupied at that time 
by Indians only. 
In 1673 there were fourteen distinct surnames among the signers of the so-called 
“Fundamental Articles.” The settlement thus began in 1672 was in 1674 made a town. 
Of the fourteen different surnames, among the original signers, ten are today (1921) 
frequent surnames in the town. 
Of these ten surnames one is, however, no longer the original Yankee name of Johnson, 
but Swedish Johnson instead. There are nevertheless, in an adjacent town, some of the 
original Yankee Johnsons. 
The chart shows graphically to what extent original names (and thus in part original 
blood) of Yankee settlers have persisted in the town. 
Columns 2, 3, 4, and 5 of the chart are, as in the case of column 1, compiled from special 
lists of property holders, proprietors of original grants, lists of taxes laid in the town, etc., 
etc. These sources contained at least the more frequent, and in standpoint of citizenship, 
the more important, names of the town. 
Columns 6, 7 and 9 are much more comprehensive. For these, lists containing 
names of all inhabitants of the town were used. Such lists were government census reports, 
special census given in Cothren’s history, or names found in vital statistics covering a 
period of thirty years. 
Column 8 contains ninety names only. This column was compiled from names of 
families to which Mr. Cothren has devoted some pages of genealogical data. Mr. Cothren 
himself told friends yet living that this list was not as full as might have been, had all of 
whom he solicited been prompt or willing to cooperate. These 90 names are therefore more 48 
EXHIBITS AND EXHIBITORS 
especially names of families sufficiently interested to provide material and assist in Mr. 
Cothren’s efforts. 
The final column, 10, is a complete list of male surnames in the town of Woodbury in 
1913-14 plus (in red ink or starred) maiden names of wives, many of whose surnames once 
known in Woodbury, were superficially extinct, i.e., the male line of certain surnames had 
ceased in Woodbury, yet the blood of those surnames was often definitely present as in- 
dicated by wives’ maiden names. 
By reading this chart across from left to right on any given surname, it can be approxi- 
mately ascertained how long the heredity of any one blood (to the extent indicated by a 
surname) has persisted in the town. 
The chart by its very nature cannot indicate how great or how small is the proportion 
of each blood line. But it does give a picture, interesting to the student of eugenics 
and heredity, of the persistence in one New England town, of surnames of original Yankee 
stock. 
It shows, as well (through maiden names in red ink or starred) what is observable in 
any study of heredity as associated with surnames, namely, the continuation of the same 
strain of blood even though the name has not persisted. 
The chart has still another phase of eugenic interest. The period of South of Europe 
immigration and later the period of North of Europe immigration are evident. Celtic 
and Latin names appear among the names of columns 6-9, while in the chronologically 
much later column 10 appear Swedish, German, Polish, etc., names. 
75. Exhibitor: Metropolitan Life Insurance Company, 1 Madison Avenue, New York,

Exhibits: Graphic charts or racial mortality in the United States. Six graphic charts 
were shown in an electrically illuminated upright stand. The mortality of the principal 
foreign born race stocks in New York State, 1910, was shown by sex, by principal age 
divisions, and for important causes of death. A table was also shown, giving the expecta- 
tion of life at age 10 for persons born in the United States of native parentage, and for 
each of the foreign race stocks by country of origin. 
Comparing all foreign born persons with the native born of native parentage, it was 
found that the mortality rates for all causes of death combined were higher after age 
twenty-five for both sexes than for the native born of native parentage. The figures for 
the expectation of life at age 10 showed that among males, the greatest expectation of 
after-life span (53.4 years) was recorded for Russian-born males (mostly Jews). Males 
born in the United States of native-born parentage showed an expectation of 53.0 years. 
The expectation for other race stocks at age 10 for males was as follows: Italian, 51.9 
years; English, Scotch and Welsh, 50.3 years; Germans, 49.4 years; and Irish, 38.7 years. 
Among females, the expectation of life at age 10 was greatest for persons born in the 
United States of native parentage (55.9 years). 
In decreasing order, the expectation for females of the several stocks at age 10 was as 
follows: Native-born of native parentage, 55.9 years; Russians (mostly Jews), 55.8 years; 
Germans, 54.4 years; Italians, 52.9 years; English, Scotch and Welsh, 52.7 years; and 
Irish, 45.9 years. 
Five charts were shown for the death rates from principal diseases and conditions 
standardized for the group of ages at and above age 10, and shown for each sex.

tus, Providence, R. I. 
Exhibits: Anthropometric Apparatus. 
Anthropometric apparatus: The apparatus exhibited by the Narragansett Machine 
Company, of Providence, R. I., is made for use in determining physical standing of the 
subject, the exercises he should take and any changes brought about by the exercises. 
Stadiometer or Height Stand: This is made according to the American Physical 
Education Association rule with the base 18 inches square and 12 inches high. The rod 
is maple, graduated to inches and tenths on one edge and millimeters on the other. The 
sliding arm is arranged to measure from its upper as well as lower surface for knee heights, 
etc. An extension of the sliding arm makes it easy to operate and read from the floor. 
Chest Depth Caliper: This caliper was designed specially for taking maximum and 
minimum chest depths at the same time. It is light and easy to handle, being made of 
aluminum and weighing only twelve ounces. The pressure is constant, being applied by 
a spring, hence the indications are independent of the observer. Its capacity is from 4 to 
10.6 inches or 10 to 27 centimeters. The scales are interchangeable. 
In use the caliper is held horizontal with the arm of the subject in the bow. 
Shoulder Breadth Caliper: This is the common form of sliding arm caliper for measuring 
chest, hips, etc. It is made of maple, graduated to inches and tenths to inches and milli- 
meters. 
Wet Spirometer: The wet spirometer is designed to measure lung capacity or maximum 
inhalation. It consists of a balanced cylinder of known volume arranged to rise and fall 
in a water tank. One of the supporting columns is graduated to cubic inches on one scale 
and to cubic decimeters on the other side. Antiseptic mount pieces are provided. 
Manuometer: The Manuometer or grip dynamometer is used for testing the muscles 
of the hand and forearm. This form records correctly all pressure applied to it, and cannot 
be overstrained or made to record high by bringing all the pressure to bear on the centre. 
The graduation may be metric or English. It is held in the hand, dial towards the palm 
and top against the fingers. 
Push and Pull Attachment: A sliding frame to hold the manuometer so that push and 
pull tests, not exceeding 200 pounds (100 kilos) may be made. 
Back, Leg and Chest Dynamometer: For making strength tests of the back and legs. 
It has a capacity of 2000 pounds (900 kilos). For use it has standard base and handle. 50

90. Exhibitor: Professor Theophilus S. Painter, Department of Zoology, University of 
Texas, Austin, Texas. 
Exhibits: One chart. The chart “The Chromosomes of Man” (plate 1, Vol I.) gives 
the essential results of a study on human spermatogenesis made by the author. Figures 1 
and 2 show that there are 48 chromosomes (24 pairs) in the germ cells (spermatosonia) 
of a white man, this number including the body labeled “Y.” The negro (figs. 3 and 4) 
shows the same number of chromosomes and the presence of the Y chromosome. In 
figures 5 and 6 the chromosomes of the white man and the negro are compared. They 
are alike in general form and in number. Figure 7 shows the ‘‘reduced” chromosome 
number of man to be 24. Figure 8 shows the sex chromosomes of man which are of the 
X-Y type. When such a cell divides, the X chromosome goes to one pole and the Y to 
the other. This is shown in figure 9 taken from a white man, and in figure 10 which is 
from negro material. As a result of this, one half of the sperm will carry an X chromo- 
some, and one half will carry a Y chromosome. Sex determination in man then is simply 
a matter of which sort of sperm fertilizes the egg. If the sperm carries an X chromosome, 
then the resulting offspring is a female, but if the sperm carries a Y chromosome, a son 
will result.

97. Exhibitor: Race Betterment Foundation, by Dr. J. H. Kellogg, President, Battle 
Creek, Mich. 
Exhibits: a. Universal Dynamometer. This instrument was devised by Dr. Kellogg 
to test the strength of each group of muscles and the aggregate strength of the human body. 
It is now in use by the United States Government at its Military and Naval Academies and 
in the leading gymnasiums of the country. The method of operation is shown in the 
accompanying illustration. The results of the tests are plotted upon graphics, which 
show in each case how the individual stands in relation to the average or normal man or 
woman. Each point which falls below the line 100 is a weak point; each point which 
rises above is a strong point. The exact amount of deviation is also recorded in figures 
along the top of this “strength chart.” At the right hand of the chart is space for the 
record of the Height-Weight, Strength-Weight and Strength-Height Coefficients. A 
comparative study of thousands of tests has disclosed the facts shown in the accompanying 
table and illustrates the value of this instrument in a precise study of muscular development 
in men and women.

polled cattle existed in the county of Suffolk, England, from time immemorial, and early SECOND INTERNATIONAL CONGRESS OF EUGENICS 
53 
historians report whole herds of red, polled cattle in the county of Norfolk, England. In 
the year 1846, these two strains were merged together and the present breed founded. 
Historical reports show that red muley cows were brought over from Norfolk and Suffolk 
by the early colonial settlers. The first real importation after the breed was thoroughly 
established was in 1873. G. F. Tabor of New York made an importation of one bull and 
three heifers. From that time on, many importations were made. 
Red Polls have always been bred and used as a dual purpose breed, the cows being 
profitable producers when used in the dairy and the young stock making an excellent 
stock cattle, fattening very readily and producing an excellent butcher’s carcass.

of 80 acres. However, the ear is more tapering, and not so cylindrical as the Reid Yellow 
Dent, more flinty after the Low Corn, and consequently is not the show ear type, but it 
weighs more per bushel as the kernels are more flinty and more disease resistant than the 
Reid Yellow Dent.

111. Exhibitor: Dr. Lothrop Stoddard, Author, 1768 Beacon Street, Brookline, Mass. 
Exhibits: Two books and a series of maps. “The Rising Tide of Color against White 
World-Supremacy” is an analysis of the movements toward greater self-consciousness and 
self-assertiveness among the non-white races of the world, which began about a generation 
ago and which have been much intensified by the Great War and the attendant weakening 
of the white races. It also discusses disgenic tendencies in white civilization, especially 
low-type immigration. 
The maps accompanying the above book (enlargements of which were displayed among 
the Exhibits at the Conference) show, in colors, (1) the distribution of the primary races 
throughout the world; (2) the Categories of White World-Supremacy; (3) the distribution 
of the white races.

consequent reversion to African barbarism as shown by the Haiti of the present day. 
112. Exhibitor: Prof. Griffith Taylor, Associate Professor of Geography, University of 
Sydney, Sydney, Australia. 
Exhibits: One wall-diagram dealing with racial variation. Professor Taylor writes: My 
research on the climatic and physiographic control of racial migration—supported by 
anatomical evidence—leads me to believe that the so-called ‘colored races’ (excluding the 
negro and negrito) are not necessarily lower in the biological scale than the Anglo-Saxons. 
I have put forward a graphic analysis of race variation, which I call the Lava-Flow analogy. 
Here I postulate a central Asiatic ‘focus of variation’, where, owing to the unique climatic 
changes, man was most subject to evolutionary development. Hereabouts all the races 
of man developed and their migrations were at first determined by the onset of the expand- 
ing ice-fields of northern Eurasia (and later by increasing desiccation). These drove away 
the forest belts toward the equator and also the animals (including man) who dwelt 
therein. When a mild interglacial period set in, the forests spread poleward again. Some 
tribes remained isolated or lost in the equatorial regions and did not evolve, for there was 
no stimulus then any more than there is now. Those tribes who returned to the central 
Asiatic region were subjected to climatic stimulus of a pronounced type and gradually 
evolved into the Hamitic folk. The onset of the next ice age led to their dispersion—but 
those who returned to or still remained in central Asia were developed into Iberian and 
Semitic peoples in the next long interglacial. So also arose the Aryan races, including 
our progenitors. These were dispersed in an irregular zone all around Asia. Science 
already recognizes the Aryan affinities of the Polynesian—but I would claim even closer 56 
EXHIBITS AND EXHIBITORS 
affinities for the Melanesians of the Solomon Islands and adjacent regions. I also believe 
that the Amerinds should be zoned in the same fashion, so that the Arawak and Carib 
peoples and many of the Plain Indians of North America belong essentially to the same 
zone as ourselves. 
Carrying this line of reasoning further, we must conclude that the peoples nearest the 
‘focus of variation’ are more lately developed than ourselves. Hence the Mongolian 
peoples of central and southeast Asia, and the more brachycephalic peoples of America 
belong to higher (i.e., later) zones than ourselves. 
The bearing of this hypothesis on the problems of racial status and of half-castes is 
obvious. It is not a racial deterioration when an Anglo-Saxon mates with a Mongolian 
or with a Polynesian or with most Amerinds. In my opinion race prejudice, rather than 
race deterioration, is the factor involved. 
The maps and diagrams exhibited were taken from my paper “The Evolution and 
Distribution of Race, Culture and Language”, January, 1921, Geographical Review, New 
York, pp. 54-119; 27 maps and diagrams.

114. Exhibitor: Prof. R. J. Terry, Professor of Anatomy, and Mr. Lee D. Cady, Student 
of Medicine, Washington University School of Medicine, St. Louis, Mo. 
Exhibits: Comparison of the incidence of the supracondyloid process in groups with 
normal and abnormal mentality (21 X-ray pictures). The occurrence of the supracondy- 
loid process in man, a variation of the humerus, has been the subject of investigation by 
a number of anatomists since its discovery in 1821 by Tiedemann. It is generally regarded 
as the homologue of the bony bar which completes the boundaries of the supracondyloid 
(entepicondylar) foramen irregularly distributed but a normal feature of the humerus 
in nearly all orders of mammals. Foramina on either or on both medial and lateral 
aspects of the distal extremity of the humerus are present in living and fossil reptiles. 
Evidence of heredity of the variation in man has been noted by Struthers and recently by 
Terry. Several studies of the incidence of the variation in man show differences in results 
and the question has been raised (Testut, Nicolas, Ferdinando) as to the possible correla- 
tion of race and also mentality with the frequency of the process in man. The variation 
is claimed to be rare among colored races; figures have been given to show a higher incidence 
among the insane than in normal people. The pictures shown here are X-ray prints of the 
humeri of two groups, normal and insane persons presenting the variation. The normal 
group was constituted by 1,000 persons of both sexes taken from the laboring class; the 
insane group of an equal number, male and female under restraint in a public sanatorium. 
Apparently the physical characters of the variation are the same in both groups. Com- SECOND INTERNATIONAL CONGRESS OF EUGENICS 
57 
paring only whites, the incidence was found to be slightly greater in the insane (1.2 per cent) 
than in the normal (0.88 per cent) and is not regarded as of significance in this investiga- 
tion. A study should be made of the incidence of the variation in a group of mentally 
superior people, in order to set at rest the question of its correlation with mentality.

Exhibits: Set of Mendel Boards and Blocks. 
Mendel Board: A device for showing, by means of movable cardboard symbols, the 
theoretical combinations in dihybrids. 
The four pockets at the top and at the left side are for the cardboard symbols represent- 
ing the male and the female gametes repectively. The sixteen pockets, forming the 
enclosed checkerboard, are receptacles for the paired cardboard symbols representing 58 
EXHIBITS AND EXHIBITORS 
the possible zygotes formed in a Mendelian dihybrid; cardboard symbols, round and 
notched, represent smooth and wrinkled peas, green and yellow for corresponding colors 
in seed coats of peas; tall and short for tall and dwarf pea vines, etc. Various other 
symbols may be employed for other characters of animals and plants. 
By this device may be shown visually the significance of gametes and zygotes, allelo- 
morphs, homozygotes and heterozygotes, dominance, segregation, the independence of 
unit characters, the results of back-crossing, etc. 
By using two gametes from each parent instead of four, and four pockets within the 
checkerboard instead of sixteen, the monohybrid may be demonstrated. 
Trihybrid Blocks: A device for visualizing the possible combinations in the F2 generation 
of a trihybrid. There are 64 blocks. Each block is made with its opposite faces alike. 
Three arbitrary symbols painted on the blocks that may represent any actual characters as 
desired, are squares, circles and triangles. On each face the symbols appear double, 
overlapping each other, to represent the zygotes formed from two parental gametes. 
When the symbols are solid black, they_represent dominants. The corresponding reces- 
sives are drawn in outline. 
With one set of symbols turned up—for example the squares—the blocks may be 
arranged in four square groups of 16 each, representing the F2 generation of a monohybrid. 
One group will be entirely made up of double black squares (pure dominants); two groups 
will each show the combination of a black square and an outline square (hybrids), and the 
fourth group will have double outline squares (recessives). This is the typical 1:2:1 
Mendelian proportion for a monohybrid in the F2 generation. 
Each of these four groups of 16 may now be arranged in four rows of 4 each, leaving the 
squares up, so that in one direction the circles, and in the other the triangles will like- 
wise read 1:2:1. The four groups of 16 each may now be superimposed to form a cube 
containing all the 64 blocks, reading independently in three directions as Mendelian 
monohybrids. The blocks may be used to demonstrate, among other things, the Mende- 
lian explanation of blending inheritance by duplicate genes. To do this, each block symbol, 
regardless of its shape, may be taken as one of duplicate genes. If now the 64 blocks 
which represent the possible progeny in the F2 generation of a Mendelian trihybrid, are 
arranged according to the number of black symbols which each shows, disregarding oppo- 
site faces, they fall into the variability curve of 1:6:15:20:15:6:1. The extremes are 0 
and six black symbols respectively. The mean, of which there are 20, has three. This 
shows that 20 out of 64 in the Mendelian trihybrid are exactly intermediate between the 
grand parental extremes and form a blend like their parents of the Fx generation, explaining 
why hybrids sometimes appear to breed true although Mendelian segregation actually 
occurs. 
121. Exhibitor: Dr. David F. Weeks, State Village for Epileptics, Skillman, N. J. 
Exhibits: Pedigree charts of epileptic families. (Plate 8, Vol. I.) This exhibit con- 
sisted of 17 framed charts, each giving the pedigree of an epileptic family represented by 
one or more members in the State Village for Epileptics at Skillman, N. J. These studies 
were made by trained field workers under the direction of Dr. Weeks. There were also a 
number of charts giving statistical tables showing the analysis of the families charted on the 
accompanying family trees and the relation between the incidence of epilepsy and asso- 
ciated factors. 
There was also shown a large circular chart, ten feet in diameter, which gave the pedigree 
connections of several hundreds of defective individuals in the same family network. 
Several members of this family have been patients at the New Jersey State Village 
for Epileptics. This study too was made by the field workers of the Village. 59 
SECOND INTERNATIONAL CONGRESS OF EUGENICS 
122. Exhibitor: Dr. H. H. Wilder, Professor of Zoology, Smith College, Northampton, 
Mass. 
Exhibits: Prints of typical palms and soles, photographs showing the technique of 
measuring a living subject, and a reconstruction of a face on a skull. 
The exhibit embraced three categories: 
(1) Prints of palms and soles, with illustrative drawings: (a) Comparative Anatomy 
of mammalian chiridia. (b) Methods of formulating palms and soles, (c) Typical 
prints, with lines of interpretation, (d) Analyses of separate patterns, (e) Instances 
of inheritance of details, (f) Palms and soles of the two types of twins. (Plate 14, Yol. I.) 
(2) Photographs showing the technique of measuring a living subject. (Plate 11, Vol. I.) 
(3) A reconstruction of a face on a skull, together with the original skull, and diagrams 
showing the method used. 
The reconstruction of a face on a skull is that first devised by Prof. Wm. His, of 
Leipzig, and employed in the identification of a certain skull with that of the musician, 
Johann Sebastian Bach. The charts shown are taken from Dr. His’s monograph; the 
skull used here is that of New England Indian excavated by the exhibitor in North Had- 
ley, Mass., a Nonotuck Algokin. This was a young man of 25-35 years. 
123. Exhibitor: Women’s Bureau, U. S. Department of Labor, Washington, D. C. 
Exhibits: Seven charts and one poster: (a) Map of United States showing States 
having night work laws for women, (b) Legal working hours for women, daily, (c) 
Minimum wage laws for women, (d) Status of women as State Labor Officials, (e) 
Legal working hours for women, weekly, (f) Two charts showing sample publications, 
(g) One illustrative poster—“America will be as strong as her women,” from a charcoal 
drawing.

125. Exhibitor: Mr. Monroe N. Work, Editor of Negro Year Book, Director of Depart- 
ment of Records and Research, Tuskegee Institute, Alabama. 
Exhibits: Charts and Maps. (Plate 42, Vol. II.) The exhibit was made up of two series 
of charts and maps. The first series was on the “Black and Mulatto Elements in the 
Negro Population for the 70-Year Period, 1850-1920” and consisted of two charts and two 
maps. Chart (1) showing black and mulatto elements in the Negro population, 1850,1870, 
1890,1910,1920 for the United States as a whole and for the South, the North and the West. 
Chart (2) showing increased black and mulatto elements Negro population in the United 
States by 20-year periods, 1850 to 1910 and for the 10-year period 1910-1920. Map (1) 60 
EXHIBITS AND EXHIBITORS 
showing the percentage by states of black element in Negro population 1850. Map (2) 
showing the percentage by states of black element in Negro population, 1910. The 
significant features of this exhibit on “The Black and Mulatto Elements in the Negro 
Population”, were: (1) the increase of the mulatto element and the decrease of the black 
element. In the 20-year period, 1850-1870, the increase of the number of mulattoes to 
each 1,000 blacks was 168. In the period, 1890-1910, the increase of mulattoes to each 
1,000 blacks was 638. For the 70-year period the increase of mulattoes to each 1,000 blacks 
was 415. In 1850 the mulatto element constituted 11.2 per cent of the total Negro pop- 
ulation, 1920, 23 per cent; (2) a comparison of the maps for 1850 and for 1910 shows 
that the mulatto element in the Negro population was being distributed uniformly 
throughout the country and that there was no section of the country where there was a 
concentration of either blacks or mulattoes. 
The second series of charts and maps was on, “The Migration of the Negro Within the 
United States”. Chart (1) showing intersectional migration 1870 to 1920; Chart (2) 
showing the gain by the North and the West and the loss of the South by interstate migra- 
tion. Map (1) showing the migration from the South to the North, 1916-1920; Chart (3) 
showing interstate migration of Negroes born in the South and living outside their state of 
birth in 1910 and 1920. Map (2) showing migration and the movement of the center 
of Negro population. The three most striking things brought out in the exhibit on migra- 
tion were: (1) the large percentage of Negroes who had moved from the South to the North; 
(2) the greatest movement of the Negroes had been within the South from the North to 
the South and West; (3) in the 130 years from 1790-1920 the center of Negro population 
had moved over 440 miles southwest from Dinwiddie County, Va., to DeKalb County in 
the northeastern part of Alabama. 
126. Exhibitor: World Book Company, publishers of school text books and standard 
tests of achievement and intelligence, Yonkers-on-Hudson, N. Y.

68 69 Fig. 6. The Chromosomes oe Man 
This chart gives the essential results of a study on human spermatogenesis, made by 
Professor Theophilus S. Painter, Department of Zoology, University of Texas, Austin, 
Texas. Figures 1 and 2 show that there are 48 chromosomes (24 pairs) in the germ cells 
(spermatogonia) of a white man, this number including the body labeled “Y.” The 
negro (figs. 3 and 4) shows the same number of chromosomes and the presence of 
the Y-chromosome. In figures 5 and 6 the chromosomes of the white man and the 
negro are compared. They are alike in general form and in number. Figure 7 shows the 
“reduced” chromosome number of man to be 24. Figure 8 shows the sex-chromosomes 
of man which are of the X-Y type. When such a cell divides, the X-chromosome goes to 
one pole and the Y-chromosome to the other. This is shown in figure 9, taken from a white 
man, and in figure 10 which is from negro material. As a result of this, one-half of the 
sperm will carry an X-chromosome, and one-half will carry a Y-chromosome. Sex deter- 
mination in man then is simply a matter of which sort of sperm fertilizes the egg. If the 
sperm carries an X-chromosome, then the resulting offspring is a female, but if the sperm 
carries a Y-chromosome, a son will result.

94 95 Fig. 19. Heredity of Musical Ability 
These charts, prepared by Dr. Hazel M. Stanton, Eastman School of Music, Rochester, 
N. Y., are representative of the results obtained in an investigation in the inheritance of 
specific musical capacities, which covered six family groups, in which one member of 
each group was known to be conspicuously talented in music. This investigation, initiated 
in the year 1920, is the beginning of the first research in heredity of talent based on quanti- 
tative measurements. Four of the Seashore Measures of Musical Talent, the sense of 
pitch, the sense of intensity, the senses of time and tonal memory were given individually 
to members of each family. These measurements were supplemented by qualitative 
information regarding individual case histories and musical experiences, the latter including 
musical environment during youth, musical training and education, musical activity, 
musical interests, and musical memory and imagination. 
On each pedigree talent chart one mating and offspring are presented showing the results 
obtained in the musical measurements, also the ratings assigned for muscial experiences. 
The results of each of the four measurements are expressed graphically in terms of per- 
centile rank ranging from 0 to 100. A rank of 98 to 100 is very superior, 90 to 97 is 
superior, 70 to 89 is excellent, 40 to 59 is average, 10 to 29 is poor. The sense of pitch is 
shown in the upper horizontal section of each individual chart, the sense of intensity in 
the second section, the sense of time in the third section, tonal memory in the lower 
section. The ratings of musical experiences are stated in terms of the letter A, high 
rating, the letter C, middle rating, and the letter E, low rating. At the side of each chart 
a brief description is given of the musical expression evinced by each individual charted.

106 107 Fig. 24. Comparison of White and Negro Fetuses 
An exhibit prepared by Dr. A. II. Schultz of the Department of Embryology, Carnegie 
Institution of Washington, deals with racial differences during prenatal development of 
man. It is based upon researches on 455 white and 168 negro fetuses ranging in age from 
the ninth to the fortieth week of intrauterine life. Fourteen plaster casts of white and 
negro specimens and ten large tables illustrate the chief points of difference in fetuses of 
the two races and in which periods of development they are most distinct. Of these 
differences the following may be enumerated: 
The average of the upper arm-forearm index for every week of fetal life is larger in the 
negro than in the white, showing that the forearm in relation to the upper arm is longer 
in negro fetuses. In an analogous way the leg in relation to the thigh was found to be 
longer in negro fetuses, a difference which becomes more pronounced with advancing 
development. The hand as well as the foot is slightly shorter and broader in white 
fetuses. In the latter, fingers II and IV are of equal length in the great percentage of 
cases and frequently finger II is even longer than finger IV; while in the negro the relation 
in length between these two fingers is more often in favor of finger IV and the latter is 
never shorter than finger II. The length of the thumb in relation to the total hand 
length is shorter in the negro, a difference which is constant and rather marked throughout 
intrauterine development. The first toe is the longest in a greater percentage of white 
than of negro fetuses, while the second toe is longest in a greater percentage in the negro. 
In the latter race the heel is more prominent than in the white. The trunk shows no racial 
differences. Of the head, the brain part is proportionately smaller and the face part 
larger, particularly in height, in negro fetuses. The nose is relatively shorter and broader 
in negro fetuses in all stages of development, causing a very marked difference in the nasal 
index of the two races. During the later part of pregnancy the nostrils are directed 
transversely in the negro and sagittally in the white. The lips are much thicker in negro 
fetuses.

146 147 Fig. 44. The Jukes 
The Juke charts compare the family as known to Dugdalein 1875 and again to A. H. Esta- 
brook in 1915, forty years later. Dugdale, 1875, while inspecting the county jails of New 
York State, discovered this family of, criminals, prostitutes and paupers, studied their 
family history and gathered data concerning seven hundred persons descended from 
“Margaret, called the Mother of Criminals.” In 1915 Estabrook studied the same family 
of people to ascertain the changes in social and mental status which had taken place in the 
intervening forty years. The charts show the two sets of data, one of course inclusive of 
the other, comparing the family at the different periods and showing that the Jukes are 
still a serious burden to the coummunity. A few Jukes have risen from the mire and are 
now socially adequate persons. Pictures of various members of the family and their 
living conditions are shown. By A. H. Estabrook.

The Nams are a set of feeble-minded folk living in the northern part of New York 
state. They are characterized by illegitimacy, prostitution, consanguinity and feeble- 
mindedness. They number about two thousand persons, practically none of whom has 
become socially adequate. The majority of the family is still reproducing its own kind of 
dysgenic folk. The charts show pictures of the folk and their homes and general habitat.
